IMPROVEMENT IN T HILL-COUPLING LOOPS.

Specification forming part of Letters Patent No. 216,291, dated June 10,1879; application filed March 14. 1879.

To all whom it may concern:

Be it known that I HENRY K. PORTER, of the city of Boston, State ofMassachusetts, have invented Improvements in Carriage Loops, of whichthe following is a specification.

The object of my invention is to provide a loop to be attached tovehicles by a bolt, screw, Or rivet, in thensual manner, and formed withan incline within the area Of the eye of the loop, such incline being soformed and arranged as to facilitate the introduction of the strapwithin and through the eye of the loop when it is desired to attach thestrap thereto; and it further consists in an intermediate bar, which isformed between the body of the loop and the end bar thereof, as will, bythe aid of the accompanying drawings, be fully set forth.

Figure 1 is a plan view, showing the loopin position as attached-to theunder side of a shaft. Fig. 2 is a longitudinal vertical section of Fig.1, but showing the shaft right side up for use, and with a section of astrap as attached to the middle bar of the loop-eye.

In said drawings, A is the shaft, and B i.

the draft-iron, secured to the under side of shaft A, the two beingunited by bolts a, in the usual manner, and shown merely to illustratethe use Of my improvements.

The loops are formed with a body, b, as shown, to receive the bolts a,and with the eye consisting of the members a c and d, all

' in the usual manner, except that the members 0 c are extended to agreater distance from the body I), and with the intermediate bar, 6,connected to members 0 o and between bar d and the body 0. To thisintermediate bar the safety-strap f is'attached, and is held up andsustained by the end bar, d, which thus confines it compactly in place,and thereby preventsits usual shaking and swinging motion,

that wears it away where it rests upon the single bar of the eye.

To facilitate the passing of the strap through the loop-eye, I form anincline, g, upon the bodyb, which incline fits closely to the iron B,and terminates at its end in a wedge-shaped joint, so that when thestrap is slid under the loop-eye and between bars 0 c it will slide upthe incline g and pass out between the side bars, 0 c.

The loops shown at the right hand in both said figures have the incline,but with the eye in the usual form.

I do not claim a harness-buckle having an intermediate bar, my inventionrelating only to that class of loops which have an eye formed upon abody, which is connected to the vehicle by a bolt or rivet which passesthrough a hole in such body, as shown in my drawings, and which isadapted to such use and to no other.

I claim as my invention .1. In a carriageloop having a body, I), toreceive the bolt a, and an eye, 0 c d, to receive the strap f, andformed upon body b, the bar 0, arranged between bodyb and bar d,substantially as specified.

2. In 'a carriage-loop having a body, I), to receive the bolt to, andastrap-eye, c c d,formed thereon, the incline g, formed upon body I) andwithin the area of the eye, substantially as specified. p

3. In a carriage-loop formed with a body, I), to receive the bolt a, andan eye, 0 c d, formed thereon, the intermediate bar, o, and the inclineg, formed upon such body and within the area of the eye, substantiallyas specified.
